3 Uses
3.1 Uses & Benefits
- Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
- Iridium has an anti corrosion properties and it is used in special alloy with Osmium metal and that alloy is used in pen tips and compass bearings.
